Regio- and stereoselective synthesis of 1-(1-halovinyl)-1H-indoles from 1-ethynyl-1H-indoles with in situ generated HX
摘要:
A facile approach to 1-(1-halovinyl)-1H-indoles from readily accessible 1-ethynyl-1H-indoles with in situ generated HX is described. The simple protocol enables a regio- and stereoselective hydrohalogenation to the triple bonds in gram-scale, and provides a general entry for novel N-alkenylindole derivatives.

A Cu-catalyzed aerobic oxidative amidation of propiolicacids via decarboxylation under air has been developed. Only carbon dioxide is produced as byproduct in this approach. The use of air as oxidant makes this method more useful and easy to handle.
